In a bid to downplay concerns about a potential conflict of interest, the bankruptcy trustee for MF Global’s brokerage customers said he’s free to probe the actions of JPMorgan Chase, one of MF’s largest lenders, leading up to the firm’s collapse.

“Certain of its actions are likely to be the subject of investigation,” said James Giddens, the trustee who’s been given subpoena power to track $1.2 billion of missing customer funds.

Giddens made the statement in a court filing to assuage customers worried about his ties to the big bank.

Giddens said JPMorgan is no longer a customer of his law firm, Hughes Hubbard & Reed, after the firm “terminated its one insignificant active representation.”
